Dead TV doesn't turn on anything or LEDs | Sk510c smd diode defect shorted on the secondary of the power supply board, position d9311 | Replace the SMD diode, you can put a silicon diode, it's even better, SR5100 100v 5a and replace the 4 470/25v electrolytics in the line, it's a good idea to replace them too. | RMC |

Connect the plug to the socket, the voltages are normal, it turns on and has audio but the screen does not light up. | The voltage 3.3v, 12v, 24v are normal, the voltage of the LEDs starts with 140v and drops to 24v. | Check the LED bars, one of them may be defective, a burnt out LED, replace it and it will be normal. | Eronaldo (erontec) |

Doesn't turn on anything, no stand-by. It has almost all voltages, but it lacks 12v for the dipslay. | Bga | Reballing lge2121, solved it the first time, before stopping turning on the TV it showed artifacts in the image etc. With this we went straight to reballing. | |
